71071077122 Wtdf/(109206721 p Be it known that I. Emit-inn hammer-in,

a citizen of thelhiited States. residii'inf at usei hicag 'o, in the county of Coo and f ted certa n new and llinois. have in n Baking: Ovens, of

which the following; is a specification.

iifiy invention relates to ba ovens and one of its objects is the provision of a simple and eflicient oven for using; heat eco-j nomically. i

further object is the provision of such an oven with air passages in its walls for permitting air to pass into the oven and absorb heat radiated to the walls ofsaid oven...

.inother object of the inventizm is the provision of air passages in a baking; oven arranged to introduce air into the oven and efi'ect the combustion of unconsumed or par tially consumed gases issuing from a heater and thereby efiect tle saving in the fuel supplied to such gas heater.

nations being Other objects of the invention will appear hereinafter the novel features and combn set forth 1n the appended claims.

An embodiment of my invention is illustrated' in the accompanying drawings, in which 1 is an end View of my improved bakingoven with. a portion broken away to show interior structure and inner parts; Fig. 2 is a side view with a portion broken away to show interior structure and inner parts; and

3 is a transverse sectional elevation of a modification. I

In the accompanying drawings 1 have shown the oven proper mounted on end spaced-apart pedestals or supportst whlch are in the form of frameshaving front and.

back legs. Mounted on the supporting frames 4 are the open frames 5 which are adapted to receive sheet metal closures to form the end walls 22 of the lowerportion of the baking; oven as shown in 2. In)

Figs. 1 and 2 I have shown semi-circular frames or castings with openings to receive closures to form end walls. at the upper portion of the oven respectively above the'end frames 5 and the closures 22 thereof. A semi-cylindrical top,.hereinafter more fully described, extends between. the upper semiedges of the frames 69 Each of the lVhen the baking oven isprovioed with a fiat topas shown in 3 flue openings may be provided at the upper central portions of the end walls similar in construction to the fines 10 shown in Figs. land. 2.

In the construction shown in Figs. 1 and 2 the frames 5 are provided with bearings 1 1 to receive the shaft 12 of a carrier frame comprising Suchshaft 12 and the spacedapart plates13 connected to said shaft and rotatable therewith. I A plurality of pan shelves or baskets i i are suspended from the rods 15 which rigidly connect the spacedapart plates 13 at spaced apart points around circumferences as shown in Fig. 1. The carriers 14 comprise horizontal plates to the ends of which. are connectedvertical triangular plates loosely pivoted to the bars or rods 15 so that when the carrier frame comprising end plates 13 is rotated the after the semi-cylindrical cover comprising the end frames 6 has beenjtilted back on the hinges 8. It will thus be seen that during the baking of the material on the shelves 14 the detachable carrier mechanism is entirely inclosed by theoven wallsand therefore the heat will be confined as desired, and furthermore the entire carrier noechanismv with rob all ofthe baked material still supported thereby may be quickly removed from the oven and replaced by another carrier mechanism with unbaked material on its shelves, and the cover. closed without altering. materially previous adiustmentsof thefbaking oven apparatus. vThe hinged coverand de tachable carrier mechanism also facilitate removal of the'carrier mee'hanismfor the purposes of repair While another carrier incense i walls, with openings in the front wall for the windct 27. Such coverings may oven in whatever shape the oven ma; be made. l i

and the door make various changes in the details and i'aneement oi parts without depa th 5:: item the s irit and SCJPG o'l my inventioo as dcfined by the claims hereto appended and l wish therefore not to be res ed to the precise construction herein disclosed.

What I wish to have piotected hvlletters Patent of thellnited States is:- I l i 1; An oven comprising: enclosin casing having; a hollow wall with a passa 'e leading upwardly from the outside atmosphere and thence downwardly into the interior-of such casing.

2. A baking oven compi'isinga nte-heat inn chamber for air entering said OVQIlfI'OIll the outside atmosphere, said ove'nbeing provided with an additional opening in its bot tom wall for receiving; heating); medium. i l

A bakingoven comprisingan enclosure adapted to receive through an opening in its under side alieating medium and provided in its wall structure with a pie-heating chamber for directing air from the outside atmosphere through such wall structure into the interior of said enclosure at a position spaced from the place where the heating: medium is introduced.

4. The combination with an oven com-i prising a casing having an upright wall with an air passageleading from the outsideatmosphere to the interior of said casing upwardly through such wall; and burnermechanism at an opening; extending througzh the bottom of said casing.

5. An oven having a portion thereof provided with outer and inner spaced r apart walls, and an intermediate partition to at- :tord an air passage from the outsideatmos-i phere adjacent the lower edge of the outer wall, upwardly over said partition and downwardly beneath the lower edge of said inner wall into the interiorot the oven.
